Cloud Security Hardening

Protect business Critical Systems

What system can be hardened?

We believe that Cloud is more secure than other environments because it relies on a strong underlying infrastructure which is more secure than most of the on premise environments built in the enterprise. Furthermore, cloud environments incorporate all the necessary security technologies in order to operate safely and securely.

It is the cloud provider’s responsibility to secure the underlying infrastructure (data center, network,  hardware & hypervisor), however it is the client’s responsibility to secure the environment he is leasing.

In this shared responsibility model, the responsibility is devided between the client and the cloud provider, the following illustration explains it in more details for three types of services (IAAS, PAAS & SAAS)

How does EXEO secures those systems?

Part of the Cybersecurity services EXEO provides is to harden the client environment in order to maximize the security of the hosted services and minimize the possibility of threats.

We have built our cloud systems hardening procedures based on the Common Internet Security (CIS) benchmarks and controls.

Based on these industry leading security recommendations, we maintain predefined checklists of controls and have developed our own standard operating procedures in order to perform the security hardening

Hardening the environment also makes monitoring more effective at detecting threats, by focusing on the incidents that require attention. If you would like to know more about how we help our clients stay secure, you can also check our managed security service page.

Re-Architect

This methodology requires the most effort to implement but it results in the most optimised recurring cost and will provide the best scalability for apps. This involves re-adapting the code of applications and the heavy use of SAAS solutions in order to replace existing hosted applications.

Re-Platform

This method utilizes the power of  PAAS services, like transferring a database to an as-a-service model,  the use of containers for some apps or the use of network/security functions as a service. Greater scalability and lower cost of operation is achieved.

Re-Host (Lift & Shift)

the migration of workloads from  to the cloud without changing the architecture. Machines get to keep their  OS and apps. This is the quickest and easy way to migrate, but since its  utilising IAAS, its is also the most expensive on the long term.
